    • The invention provides in one aspect a suspension testing apparatus which uses air bearings (96) which have a low coefficient of friction. The invention provides in a second aspect suspension testing apparatus which ensures accurate measurement of suspension characteristics since the apparatus applies forces directly below the centre of the vehicle wheel hub (12) (or forwardly or rearwardly therefrom at a distance equivalent to the pneumatic trail of the tyre in the wheel (12)) to ensure that the point of application of a force remains constant despite rotation of the support means (10) for the wheel (12) during deflection of the vehicle wheel (12). The invention in a third aspect provides new sensor means (22) for measuring the vehicle wheel deflection which uses a minimum number of transducers (162, 163, 164) to accurately monitor tyre and wheel deflection during use. The invention provides in a fourth aspect testing apparatus which uses mechanical actuators (15, 23) rather than hydraulic actuators to cause motion of the support means, which give an indication of the displacement of the support means. In a sixth aspect the invention provides a method of testing a vehicle suspension using the apparatus of the invention.
    • 本发明在一个方面提供一种使用具有低摩擦系数的空气轴承(96)的悬架测试装置。 本发明提供了一种第二方面的悬架测试装置,其确保对悬架特性的精确测量,因为该装置将力直接施加在车辆轮毂(12)的中心下方(或者向前或向后的距离相当于 轮胎(12)),以确保尽管在车轮(12)的偏转期间用于车轮(12)的支撑装置(10)的旋转,力的施加点保持恒定。 本发明在第三方面提供了用于测量车轮偏转的新的传感器装置(22),其使用最少数量的换能器(162,163,164)在使用期间精确地监测轮胎和车轮的偏转。 本发明在第四方面提供了使用机械致动器(15,23)而不是液压致动器来引起支撑装置的运动的测试装置,其给出了支撑装置的位移的指示。 在第六方面,本发明提供使用本发明的装置测试车辆悬架的方法。

    • This horticulture system mixes and meters two liquids in precise and determinable quantities and provides for appropriate control of the liquid flow. A water tank and a chemical tank are respectively coupled by constant volume pumping means to a mixing and discharge nozzle means. The pumps are driven by a common motor to obtain a predetermined flow ratio. A pressure responsive bypass valve means is connected between the output side of the pumps and the respective tanks to provide an automatic bypass of the respective liquids to their respective tanks in response to the opening and closing of the discharge nozzle. The bypass function of the bypass valve is controlled by pressure generated in the system. Bell means are provided to respond to the presence of flowing chemicals in the chemical output line to indicate that a metered volume or flow of chemicals is occurring and to provide an indication of the relative flow volume. The bypass valve includes an improved pressure responsive system which is adjustable for differing line pressure conditions.
